FIX: Chat messages exporter (#25461)
We usually don't enforce foreign key relationships on the database level. 
Because of that, occasionally it's possible to see a chat message that 
references to a non-existent chat_channel or user. MessagesExporter 
failed in such case before, this PR fixes that.
